An insider tells Us that the NYC-based pair, who tied the knot in 2009, decided to call it quits in the summer of 2016. Another source adds that Mosberg was on the exclusive, members-only dating app Raya back in July. The app is a favorite among celebrities such as John Mayer, Jeremy Piven, Chelsea Handler and Matthew Perry.

In February 2016 Kirke, 31, told TheTelegraph that she met Mosberg — with whom she shares daughter Rafaella, 6, and son Memphis, 4 — during a rehab stint for “everything … partying” in her 20s.

At the time of the interview, the British actress (who plays Bohemian Jessa on Girls) told the U.K. publication that Mosberg was in the process of setting up a rehab center, The Hook Recovery Center, which is now open in Red Hook, Brooklyn. Kirke also said that she had started drinking again, socially — a decision her husband was initially worried about.

“Mike was nervous at first. He said, ‘Look, I would never tell you what to do; you are an adult — just don’t f–k it up.’ He had every right to be scared, he knew my story,” she told The Telegraph. “But I was a different person back then. I was in my early 20s. I didn’t have children.”
